Application program integrity verification method and network device

Abstract

Embodiments of the present disclosure disclose an application program integrity verification method and a network device. The method includes: performing eigenvalue calculation on data of an application program when the application program starts, to obtain a first digest of the application program (101); decrypting a stored digital signature of the application program according to a public key in an embedded key pair to obtain a second digest of the application program, where the digital signature is obtained, according to a private key in the key pair, by signing data of the application program each time the application program is updated (102), and the key pair is a manufacturer key pair corresponding to the application program; and determining that integrity verification of the application program passes if the first digest and the second digest are the same, otherwise, determining that integrity verification of the application program does not pass (103).

Dependencies are inferred from the claim text.
